The Schiff test named after Hugo Schiff is a chemical test for the detection of aldehydes. An unknown sample is added to the decolorized Schiff reagent and when aldehyde is present a characteristic magenta or purple color develops. The Schiff reagent is the reaction product of Fuchsine and sodium bisulfite. Human skin also contains aldehydes and gets stained as well.
